LIQUID DISPENSING CLOSURE CAP Filed March 6, 1959 United States Patent 2,979,219 LIQUID DISPENSING CLOSURE CAP Domenick P. Barravecchia, 54 Stillman Ave., Westerly, RI.

Filed Mar. 6, 1959, Ser. No. 797,661 4 Claims. (Cl. 215-'-65) This invention relates to closure means for liquid cont ainers and constitutes a -continuation-in-part of my copending application Serial No. 661,408, filed July 24, 1957, and entitled Combined Cap, Valve and Dispensing Spout for Liquid Containers.

More specifically, the present invention relates to a closure cap for conventional beverage containing bottles having a reduced neck portion which terminates in a beaded end.

One of the primary objects of this invention is to provide a cap for conventional bottles with means for releasably securing the cap across the open end of the bottle.

Another object of this invention is to provide a' closure cap of the type generally described with unique means for quickly and releasably securing the cap on the open end of the bottle or container.

This invention contemplates, as a still further object thereof, the provision of a closure cap for a bottle or container together with means for releasably securing the cap on the open end of the container, the. means being non-complex in construction and assembly, inexpensive to manufacture, and durable in use.

Other and further objects and advantages'of. the instant invention will become more apparent from a consideration of the following pecification when read in conjunction with the annexed drawing, in which:

Figure 1 is a perspective view of a closure cap constructed in accordance with this invention, the cap being illustrated as releasably connected to the open end of a bottle or container;

Figure 2 is an enlarged detail cross-sectional view of the closure cap, and of the releasable securing means, Figure 2 being taken substantially on the vertical plane of line 2-2 of Figure 1, looking in the direction of the arrows;

Figure 3 is a bottom plan view of the closure cap illustrated in Figure 1, Figure 3 being partly in section and taken substantially on the line 3-3 of Figure 2, looking in the direction of the arrows; and,

Figure 4 is an enlarged detail cross-sectional view of the closure cap with the releasable securing means moved to its inoperative position to permit the cap to be removed from the bottle or container.

Referring now more specifically to the drawing, reference numeral 10 designates, in general, a closure cap constructed in accordance with this invention and adapted for connection with a liquid container or bottle 12, the contents of which are to be dispensed. The cap 10 is seen to comprise a substantially hollow cylindrical member 14 including a side wall 16 having a depending integrally formed arcuately shaped clip 18 extending from one end thereof, and an end wall 20 extending across and closing the other end of the side wall 16. A resilient sealing element 22 formed of rubber or other similar material is disposed within the cylindrical member 14 and substantially fills the same. As is seen in Figures 2 and 4,

. Patented Apr. 11, 1961 the end wall 20 and sealing element 22 have confronting abutting sides.

A discoidal member 24 having an area substantially equal to the area of the end wall 20 is rigidly secured thereto in face-to-face engagement by conventional means. The member 24 is provided with an integrally formed laterally and outwardly extending tongue 26 from which depend a pair of laterally spaced integrally formed standards 28, 30.

Reference numeral 34 denotes a substantially U-shaped lever which includes a bight 36 from the opposed ends of which project a pair of laterally spaced and substantially parallel side arms 38, 40. As is seen in Figures 2v and 4, the bight 36 is longer than the width of the side arms 38, 40, and the bight 36 terminates in an upwardly inclined flange 42 forming a second clip.- From Figure, 3 it is seen that the outer end of the second clip or flange 42 terminates in an arcuately shaped end 46. The lever- 34 is pivotally supported on a pivot pin 48 which extends through the side arms 38, 40 and has'its respective opposed ends fixedly secured to the standards 28, 30.

Reference numeral 50 designates, in general, a second lever. This lever is seen to be substantially U-shaped in configuration and includes a pair of laterally spaced and substantially parallel side walls 52, 54. The side walls 52, 54 are each provided with cam surfaces 56, 58 at their respective upper ends which continue into substantially planar extensions 60, 62. The bight 64 of the second lever 50 extends at one of its ends beyond the side walls 52, 54 to form means for manually operating the lever 50. As is seen in Figure 2, the free end 64A of the lever 64 is arcuate'ly curved for positioning in spaced relation relative to the container 12 to provide finger space therebetween when actuating the lever 50 from its operative locked position to its unlocked or released position. The

The above described device 10 is designed to be'usedj in conjunction with a conventional beverage containing? bottle 12 having a reduced neck portion 68 whichterniinat'e's-in a' beaded end 70'. To utilize the device'10, ref

erence is made specifically to Figure 4 of the drawings.

In this figure the component elements of the device 10 are illustrated in their respective positions as the closure cap 10 is being connected to the open end of the bottle- 12. As is shown in this figure, a portion of the bead 70 of the bottle 12 is received within the hollow cylindrical. side wall 16 and abuts the adjacent side of the resilient: sealing element 22. The first clip 18 is made to engagearound the bead 70 after which the bight 64 is pivoted downwardly in a counterclockwise direction to cause the:

flange 42 to engage below the bead 70 on the diametrical opposed side of the bottle 12. As the bight 64 isrotated in the manner described, the cam surfaces 56,v 58 ride against the underside of the tongue 26 and the flange or clip 42 becomes fixedly locked against the head 70 when the planar extensions 60, 62 engageagainst the underside of the tongue 26.

The closure cap 10 now assumes its position relative to the bottle 12 in the manner illustrated in Figure 2.

When it is desired to remove the closure cap 10 from: the bottle 12 to dispense contents therefrom, the same is accomplished through the simple expedient of rotating the bight 64 in a clockwise direction to cause the lever 34 to pivot and effect disengagement of the flange 42 from beneath the bottle bead 70.

Having described and illustrated one embodiment of this invention is to be limited only by the scope of the appended claims.
